Aike symbols refer tov like parts wherever they occur. 'The power fordriving the machine may be derived from any suitable source es. for

instance the 'drivingshaft B. locuied :it one end of the machine. B vmeans of beveled the driving shaft B sctuates continuouslj.'-theiferticel shaft B. mounted in suitable heelings upon the frame ofthe machine. The vertical shaft B', through heveledgears ectuates thehorizontal shaft B2 upenfwhich is mounted one of n pair of feed rolls. C(ses Figs. l and 7). through which he'ipeper begs are introduced intothe machime in the preliminary operation oi forinimgfthe indiiiduelpiles or packages. rlfhe upper member of the set of feed rolls C ismounted upon e shaft b2 which is driven jfrorna. spur geur upon'theshafts B1'. 'The sha B2 (see Fig. e). likewise drives the Shaft B3vwhich lutter isprovided with :i :inhiber of beveled gears which in turndrive 9.5 the' horizontal shafts B4 through the intermediecy of beveledgears upon said shafts. The several shafts B4 have mounted upon them thelower members of the sets of feed rolls or 'eerrier rolls C', C?. C3,the upper es member of these setsv of rolls being mounted upon shaftsb4. which' are driven h v spur wheels, as'sliown in Figs. 1;.2 and 7.from she shefts B4. Additional shafts Pf. how

mounted upon them the rolls C4 are like- 105 wisedriren hy spur gearingfrom individnel memleersof the series of shafts B4. The function of thesets ol2 rolls (l. C2 und C3 is to` feedtlie hugs into the machine in :ihorizontal d-irec-ion, and the function of the 130 rolls C4, cooperatingwith 'the lowermost of the 4pairs of rolls C asnd C3 respectively. is to*feed *the bags downwardly into the piling` mechanism. when the switchesC are appropriately adjust-ed for that purpose.

"By reference to Figs. l1 and 1Q. it will he .noted-'that the frontshaft B* is provided with hubs (Y mounted looselyv to rock thereon, fromwhich hubs project the arms (16,705, the outer ends of the arms C and12o oeierends of the arms CS. being connected by crossfplaltes C", sothat the two hubs and theirfmns'may rock together. Attached totiieiipperplete C are the switch plates C5, which, asebove stated, serveas guides for 125 directing the bags from a horizontal to e verticalpath of movement.

@ne-of the `arms C8 is connected, by means ofe rod C with e bell cranklever C11 atcaqhedftolthe rod C4 (see'Figs. 4, 5 and 7), 13@

which, in turn is connected to the piece Cx8 and consequently to theslide C which norks in the guides C. Attached to the slide C is a studor projection' C (see Figs. 13 and lll near the upper end thereof, andhelmv this stud C is :i pin C to which attached one end of a spiralspring C28, whose other end attached to aV pin (12 on the vvheel C. Thewheel C15 is fixed upon and x'fitatb with the shaft B1". whichI is sogeared to the pilinglr mechanism as to make one revolution for themaximum number of bags (say one hundred) to be included in a singlepackage.

The Wheel (im is provided with two Slots C1" arranged diametricallyopposite each other in a peripheral flange of the Wheel. During on(Jhalf of the revolution of the. wheel C. the stud C15 rides either uponche outer or inner periphery of the Wheel iiange, :is *he case may be.thereby maintaining the rod C at the upper or lower limit of its throwand consequently maintaining the forrrarfl switch C5 either in positionto divert the bags downward to the first piling device, or to pass rhemon to the second piling devine. 'whose switch is stiitionar)y and is notronnw'hid to the shifting mechanism. InaS- nnieh as' the spring;r Crevolves with the Wheel. the sind C15. as soon as either of the slots Ccome into alinement with it, is pulled through said slot. in the onedirection or the other as the rase may be. and the switch isaceordinfrl;y shifted. As this shifting takes place with each halfrevolution of the Wheel, it if; evident that one half (say Fifty), ofthe number of the bags fefl into tbemaeliine during the, period ofrevolution, is supplied to the fir-sit of the piling devices. and the.second half (the remaining fifty) 'to the second of the piling devices,and so on alter- Natel),v during rontinned revolntione of the Wheel.

The rollers C and C* and`the rollers C? and ("4 direct the bags one b vone tothe piling or assembling devices for the' individual packages.These piling or assem bling devices are shown as arranged intwo sets'and are preferably ,of the construction 'shown more particularlyr inFig. 9. For convenience. I will designate them as paddle Wheels. whichthey roughly resemble, and `"vill describe them h v the application ofcapital letters voi" reference only. it being un# derstood that theparts denoted in the drawings h v the corresponding vsmall letters areof similar construct-ion and perform similar hinctions. These paddle"Wheels 'C32 are mounted upon shafts C and on opposite sides of an.intermediate qnide wav. Each paddle wheel is provided. in thisinstance, with eight sets of tangential pockets. the pockets of eachpair of paddle wheels cooperating with each other to receivesuccessively the individual bags as they are-fed with the cam tract B10upon the shaft whereby the progressive, intermittent motion above.referred to is imparted tothe two sets of paddle Wheele. The shaft B9may conveniently be driven from the shaft B through the. intermediacy ofthe spur gears B". BUB.

As the bags are successively delivered from the paddle wheels they areassembled againsta hack-stop C or C4", one. of which is provided ioreach pair of paddle Wheels. Plate-s C38, C (see- Fig. 6) are fastened tothe hack-stop and serve'as a moving platform to support the bags as theyare discharged from the paddle Wheels. Coperating with the lrst set ofpaddle Wheels is the pusher C36 and with the second ser of paddle wheelsthe pusher C39. These pushers, together with the back-stops C57 and C.are mount-ed to slide upon the slideways C54. The pusher C3 ias-providedwith an aetnating rod C and the pusher C3 is provided with an actuatingrod 0'. So also the, back-stop C is provided with an actuating? rod Cand `vthe back plate 04 is provided with an actuating' rod C. Theseseveral actuating rods (see `igs. 4,' 1 and 7) are connected to acorresponding series of @am -actuated levers C. Whose free' ends hearupon ille enter edges oi the. cam tracts C, C25, (725 and C. which camtracts are formed iipon the disks C22. C23 .\vhich are attached to thewheel C with a capacity for adjustment, by means of bolts and nutsengaging'with the slots C (see Fig. 5). The cam levers C43 referred toare mounted upon a stationary pin or axis'C, attached to tho frame-Workand the free ends of. the cam levers yare held in Contact Witlrthe camtraets .'by means of springs, as sliomi. The. cam tracts and cam leversare so'constructcd and amanged, that when sav fifty bags have heendelivered b v the paddle wheels against each of the back plates, theback plates and pusheis will move rearwardly into alim.- ment with thestationary guides C3 on the table Us, as is indicated in Fig. (i for thefirst set of paddle Wheels n'liirh has, in its adjustment. received anddelivered its full quota of bags to its back-stop C".
